- A viewer asked what components are needed and what the cost would be to run a 18,000 btu mini split heat pump ac unit on off grid solar during the day and battery bank at night. We show the components, cost and where to buy the components with links in description. We share different ways to set up system. Check out our 100+ videos on off grid solar. We have been running off grid solar for over 3 years now in Phoenix AZ. We are all electric at our house and use solar off grid to run our ac units 7/24, pool pump and pool heater. Freezers, fridges, stoves and cooktops, oven, washer, dryer, outdoor lighting, garage lighting, hybrid solar roof vents and more. No solar panels are on our roof except for hybrid 40 watt exhaust roof vents. We are able to start our 3 1/2 ton, 4 ton AC units and our 17,000 btu & 127,000 btu pool heaters using just solar to run. Our electric bill will now be below $100 a month every month for living in the hot desert in Phoenix AZ. Check out this video and other videos on hot we accomplish this and what components we used. We are jut DIY people who did not know anything about ac units or solar 4 years ago, we did all the solar off grid ourselves saving us up to 75 percent off cost. We bought all used solar panels locally for $25-38 each (250 watt-330 watt solar panels). Hope you enjoy the video and please like, share, subscribe and smash that notification bell as well.

LifeP04 is a game changer when it comes to off grid. I started out with a deep cycle in my shed to run a 40Watt LED light connected to a small 400W inverter. It could hardly keep up I found cheapest 100-amp LifeP04 battery off Amazon about $230 on Prime day. What a difference it can go to a much lower voltage, and charge lot faster which is what you want for solar. My battery charges up off 2 265W Q cells in an hour. Now I have a small window AC unit in the shed with high temps in Phoenix right now can't keep up I'm using Utility power during off peak in the day. Then I run it off the panels during 4-7pm peak time. I'm thinking of expanding EG4 system and batteries is a great deal 100 amps at 48V for about $1300. Doing some quick research, I calculated could build a DIY off grid system for about $1.15$ a watt. I could be wrong but be cool to do some real calculations using Santan solar used panels. EG4 can be synced together along with the batteries.
It is an investment but I spent around $5000 a year for last 4 years and system will have paid itself off in December of 2023 with just electricity bill savings. Thanks for your wonderful input and hope you have a wonderful and truly blessed week
Excellent presentation...well discussed...soft start on ac would help...respect from baltimore
Thank you, we appreciate your input. The mini splits do not need soft starts since they start up slowly with watts being used. Great for solar and very efficient. DIY install is easy.
$15-20K is adequate, depending on your location. When your neighbors are out of power, can’t get to town due to ice or the gas station doesn’t have power or internet and can’t sell you gas…you’ll still be warm and making coffee. It’s silent, doesn’t stink, rarely breaks.
You are correct. The best part is the system is already paid itself in savings. Now it is just free electricity from here on out. Recouping your cost in less than 4 years is a great investment. Especially since out kw cost has almost doubled in just 2 years. I have 20 extra solar panels in case I need to replace some down the road and back up inverters. Thanks for your input. Hope you have a truly wonderful and extremely blessed New Year.
I would love to be off grid like you guys!
Sent you info in the other comment, see that response
Great Explanation thank you.
You are very welcome, I try to explain in layman terms because 3+ years ago I knew nothing about solar off grid or mini splits or hvac. I love showing what is possible with solar and installing it yourself. Glad you liked the video
I think I might upgrade to a 18000 BTU mini-split myself I was afraid they would pull too much power but from this video I might be able to handle it I also have a 220v MPP Solar similar to the one you have on the wall sitting here on my floor been sitting there doing nothing for about a year now
Dry easy to install both and easy to connect. Mini splits are so much more efficient especially when you get room to temp set. Than you hardly use any power. Thank you for your input.
Nice reviews.
Thank you
Just get you an EG4 hybrid mini split No inverters needed you connect directly from the solar panels to the unit, I have four 400 w Canadian solar running to an EG4 hybrid mini split with no inverter and it works flawless.
Very nice, I want to get one of those mini splits as well. Thanks for your input. Hope you have a very wonderful and extremely blessed 2024.
Not sure what type mini split you're using. I have 4 of them (1-24,000, 2-12,000, 1-18,000 btu) and none use that amount of amperage. I live in the desert too. The 24,000 btu has been connected to a 15 amp/240 volt breaker for 3 years without ever tripping a breaker. Amp readings at the unit measure 2 to 8 amps per leg (range). Also instead of buying premade lithium battery banks, I was able to build a 11,500 watt/hr battery for under $2000 using 16 - 230 a/h (3.2) prismatic batteries in series along with a JBD bms. Even with a Victron 150/35 charge controller the cost was barely above $2000. I was able to purchase a Sigineer split phase 6000 watt inverter (also charges off grid or generator) for under $1200. So, for less than you paid for your 4800 watt/hr EGXyG748921 battery, I built an 11,500 watt/hr battery. 2-1/2 times the storage for the same money. You need to remind your viewers that it's always better to build yourself if at all possible. And perhaps get your mini-split checked out. I owned an hvac company for many years so I have a bit of experience with unit amp draws. I saw a lot of waste in your system. Overkill, if you will. And YOU CAN used mixed panels with the proviso that your output will be diminshed to roughly the least pane's output. If you can feret out the very weak panels and eliminate them it's possible to produce output using mixed panels that is good. And if you buy large lots of used panels, you can test them and match them for some pretty good results. Many of the used panels are down in output and thus the reason for their replacement.
Thanks for all that information. Hope you have a wonderful and blessed week
Where can we see _Your_ DIY video? I would be very interested in your setup. Thanks!

I am able to start a 3 1/2 ton and 4 ton central heat pump and a 12.7 ton heat pump pool heater with these 2 Growatt low frequency off grid inverters. Mini splits slowly ramp up, but these heat pumps have a huge surge at start up. It is not overkill on system. It is what is required to start very large loads. You won’t be able to start these heat pumps with that set up. You can build your system the way you want but you shouldn’t criticize others for building their system the way they want to. You are comparing apples to oranges thinking you are comparing apples to apples. The whole point of DIY is to build a system that makes sense for your own unique situation, I should not try to build my system according to what you want me to build it to since you have no clue of what I need to run with my system. Someone asked me a question and I answered it with the equipment I have. It is reckless when viewers go off on a tangent. The viewer did not ask you the question or ask for your opinion. You seem to assume a lot in your comments and assume anyone else that does not do it your way if wrong. I am happy you built your system the way you wanted to. I have no problems or suggestions for you for your system. You built it according to what your needs are. I built my system while going through 2 incurable caners that I still have to get treatment every 8 weeks along with the extreme pain and side effects. Built it all by myself taking days and weeks to accomplish what you probably did in minutes or hours. I can only work solar for a few hours a week due to limitations I have. Some times I can’t work on it for weeks at a time due to pain and infections. So comparing what you built to what I built makes no sense. I am greatly limited by my condition. Maybe you could think about this before you try to make a DIY person look stupid on purpose to try and make yourself look smart. I think a smart person shares what they accomplish with others at no cost to them except their time. That is what I am trying to do. I could of deleted your comment but wanted to take the moment to share facts you knew nothing about so that maybe you don’t do this to others. Sharing what you built is wonderful. Trying to make others look stupid on their own channel is prideful and makes you actually look bad in the end. I forgive you and hope you will in the future share your what you accomplished and stop there. I hope you truly have a wonderful and extremely blessed week
Good afternoon Pappa, I'm assuming you sold the AGM batteries?
Yes, they are long gone, ended up giving to my brother. He is enjoying the off grid solar experience with a 12,000 btu mini split lowering his electric bill. Hope you have a truly wonderful and extremely blessed 2024
This is kinda not up to date information? You can buy a 1200BTU EQ4 AC/DC mini split Seer2 22 with no inverter no batteries and a built in AC limiter for about $1300.00
Max 380 volts min 90 volts. Im running one on 4 370 watt panels in series.
You are correct, you can get direct solar connect mini splits now that can run during the day with no inverter or batteries provided you have enough solar connected for cloudy days or rainy days. Thanks for sharing.
I bought the 38 seer minisplit and it is 220 volt 9000 btu. It goes as high as 13500 and as low as 2000 btu. I easily run it 24.7 when im not im my semi truck. I ran it non stop off of 7kw of battery and 1850 watts of solar. Ive now upgraded to almost 30kw of battery but that runs my whole camper with the ac. I think the high seer units use about half the power of the cheaper units. Mine takes 200 to 300 watts to run 24.7 it takes a little over 600 watts to cool the camper down but yeah 2 or 3 hundred once its cool
Very nice, I can’t wait to install and try a high seer mini split in my motor home.trying to find flexible solar panels to install on roof but still investing weather worth it. Thank you so much for your input. It helps all of us doing DIY solar when you leave comments like this. Hope you have a wonderful and blessed week
@@diy-solar-guy I started to use flexable panels and just use vhb tape to secure them to the roof. At the moment I have 1850 watts on aluminum ground mounts but the flexible on the roof in my opinion would be the way to go but they are kinda expensive. I bought used panels but they work great. I'm looking at getting 10 or 12 more this next week. The solar project has taken my mind off of being sick and given me so much happiness and satisfaction and feeling of accomplishment when I'm home and it's all working. Thanks for the conversation and you have a great week also. Happy 4th
@@matthewknight5641 thank you so much. Happy 4th
What brand/model was your 38 SEER mini split?
@@ernestgalvan9037 inovair 38 seer 9000 btu. It's a 220v model and I run it from a sungold power inverter. The sungold inverter is way overkill. It would run on a lot smaller inverter but the only one I had that was 220 is the 4000 split phase sungold
Hello I am in Phoenix area on the westside. How many batteries do you have and how much do you want for them? Are you for hire to install a solar system just for my mini split in the garage? i have solar for the house already and not so happy with the results.
Hi, I am in the southwest corner of Phoenix. I have 16 AGM batteries, want $100 each. I use the AGM batteries only during the day. Just using they batteries to run ac in house during the day reduced my electric bill over 60 percent. I had 4 separate 24 volt 120 volt output inverters in parallel at the time that could run 5 mini splits. I can show you how to install mini splits and set up off grid solar but physically I am unable to do installation. I am going through some medical issues., I can show you how easy it is to install yourself. Actually took me 6 days to install mini split in motor home. Had to use hard core prescribed pain killers day and night.That would probably take you 2-4 hours to do the same. On grid solar is not a good way to go here in Phoenix due to the utility company punishing you to go solar. They are loosing income when you go solar. They wanted to raise my electric bill to a minimum of $125 month. That would be even if I produced 100 percent of my own power. My winter months are $60 now and $100-$150 in most summer months.I would be happy to explain and show you how to do it yourself since you live so close if you want to contact me. An email to contact me ppag53421@outlook.com. Contact be and I will help the best I can. Hope you have a wonderful and blessed day
What size of charging controller would you need for that system for mini spilt but my mini split is 110v off grid and what size of inverter
At least a 24 volt pure sign wave inverter. You can connect between 2400-3000 watts in solar panels. You could run 2 mini splits with that system.
Wow
Thank you for you input. I appreciate it very much.
How much do you want for the batteries for sale
Looking to get $125 each, I have 16 total. Using those in the day only running mini splits on solar saved me over 60 percent on electric bill.
Basically you need a million dollar system it seems.
With inflation the way it is going, that’s about right.
Not necessarily, you just have to be willing to shop around. I put a decent system together for about $5000. Not all at once of course.
@@asus12351 exactly, this is an investment that will pay off saving you a lot of money down the road. I invested $20,000 over 4 years and the system has paid itself off in savings already. This year will be free electric. Our electricity rates have almost doubled in just the last 2 years. My electric bill will continue to be low all year long. I over produce so I can save even more by adding more things around the house to run on solar power in day and battery bank at night. Thank you for your comment. Hope you have a wonderful and blessed week.
Are you still considering selling your AGM batteries. Richard
Yes I am still selling the AGM batteries. Have to be able to pick up locally. 4 for $600($150 each)or 8 for $1000($125 each). I have a total of 16 AGM batteries. I used to run my 3 1/2 ton upstairs air conditioner and 2 mini splits downstairs from 8 am to 5 pm daily using these AGM batteries. I had 4 sets of 48 volt battery banks in parallel. Never let go below 12 volts each. Did not use overnight. Saved 60 percent off electric bill using these batteries during the day. Using the LiFePO4 batteries overnight really only saves me another 25-30 percent. But LiFePO4 were really expensive. With this weather I run my LiFePO4 batteries down to 20 percent overnight and some nights when temp is 115 or more I still run ac on grid power so I have 100 LiFePO4 battery bank in morning to start cooling house at 6 am. Let me know. Hope you have a wonderful and truly blessed week
Sorry more than I thought. Good luck. I live in Mesa Arizona
@@galenluth4347 thank you for your reply
I wanna know what that salt and peper dogs name is
Oh, you finally saw some puppies in the video. It was tough but I convinced them to get in video.
